Step 3: Neutralize. Create a thick paste out of baking soda and water. Apply to the spill to absorb it. Wait 1 or 2 minutes. Wipe up the mixture with paper towel and immediately put the soiled paper towel in the plastic bag. Apply another layer of the baking soda paste.
Causes of Bare Spots in the Lawn. Bare spots in your lawn can be the result of heavy foot traffic (causing soil compaction), drought, disease, chemical burn and weed or insect infestation. Before beginning repairs, you need to determine the source of your problem.
The build up of salt in the soil can cause spots in your lawn to dry out if the grass is not watered sufficiently. In most cases your lawn will need 1 inch of irrigation water or rainfall every week to prevent dehydration.
